I appreciate thinking out of the box to realize your dreams/goals!
25+ years ago I had a friend who lived in his parents’ “tailgate RV” for his last couple years of pharmacy school (I was undergrad at the time… same univ). He had the RV parked at a mobile home park with access to amenities.
I don’t know if this option makes sense economically today or logistically in your locale, but anecdotally I could see it as an option worth exploring.
Good luck!
